FilterMenu loses its style on customization

Hi,

I have been trying to customize the FilterMenu items for different columns in a RadGrid. I want it based on the Data Field associated with the column. I am able to implement it but the problem is with the behavior of the menu items. Items seem to be clipped inside the menu. I mean the hover effect is not properly setting the background color of the current item. Although, on removing the javascript code (to hide the filter functions), the filter menu behaves as expected.

I am attaching the snapshots. I have used the code used in this demo :
http://www.telerik.com/help/aspnet-ajax/grid-reducing-filtermenu-options.html

I want to customize the FilterMenu items based on the column name, Left align them and have a constant look and feel(as described in snapshots) for the hover effect.
Any form of help will be appreciated.

Regards,
Anup

string value of radbombobox javascript

Hi,

im trying to extract the value of a radcombobox. Previously this value was stored in a regular asp textbox, then I could do like this to get the last part of the string value in js.

Right(document.getElementById('Mybox').value, 5) < 1000

this number is built up like so. 'project-module-1xxx'

I.E I only want to get values that are higher than 1000. How can I get the same functionality from a radcombobox ?

I tried with

Right($find("Mybox").get_text(), 5) < 1000) but that didnt recognize the right functionality.

all help appreciated,

ComboBox

RadTreeView1.GetXml not saving client side node state

Hi all,

I'm using RadTreeView1.GetXml to save the state of my TreeView and repopulate it after postbacks.

I've done a test by replaceing text in a node, and based on that I can tell that saving and repopulating the TreeView is working fine.

The problem is that when I contract some of the nodes, then select(Click on) a node, there is a posteback, and all the nodes are revertted to thier expanded state again.

Expanding and contracting nodes seems to be happening on the client side, as there is no postback when this happens.
The postback dose happen when I click on a spesific node, that is when I use GetXml to save the state, but it dose not seem to be saving the updated state on the nodes.

Here is the code, Please let me know what I am missing here.

<telerik:RadTreeView ID="RadTreeView1" Runat="server"

OnNodeClick="RadTreeView1_NodeClick" EnableDragAndDrop="True" Skin="Vista"

OnContextMenuItemClick="RadTreeView1_ContextMenuItemClick"

OnNodeEdit="RadTreeView1_NodeEdit" OnNodeDrop="RadTreeView1_HandleDrop"

SingleExpandPath="True" EnableViewState="true" >

<ContextMenus>

<telerik:RadTreeViewContextMenu ID="RightClick" runat="server">

<Items>

<telerik:RadMenuItem Value="NewParentNode" Text="Create New Parent Folder" >

</telerik:RadMenuItem>

<telerik:RadMenuItem Value="NewNode" Text="Create New Folder" >

</telerik:RadMenuItem>

<telerik:RadMenuItem IsSeparator="true">

</telerik:RadMenuItem>

<telerik:RadMenuItem Value="NewVirtualDocument" Text="New Virtual Document" >

</telerik:RadMenuItem>

<telerik:RadMenuItem Value="UploadPDF" Text="Upload PDF" >

</telerik:RadMenuItem>

<telerik:RadMenuItem IsSeparator="true">

</telerik:RadMenuItem>

<telerik:RadMenuItem Value="DeleteNode" Text="Delete Folder" >

</telerik:RadMenuItem>

</Items>

<CollapseAnimation Type="none" />

</telerik:RadTreeViewContextMenu>

</ContextMenus>

</telerik:RadTreeView>

and server side

protected void RadTreeView1_NodeClick(object sender, RadTreeNodeEventArgs NodeEvent)

{

clickedNode = NodeEvent.Node;

ViewState["ClickedNode"] = clickedNode.Value.ToString();

createDynamicTable(Convert.ToInt32(ViewState["ClickedNode"].ToString()));

string savetreeViewState = RadTreeView1.GetXml();

savetreeViewState = savetreeViewState.Replace("South Africa", "save state is working");

Session["myTreeView"] = savetreeViewState;

}



Thank you for your time.

How Can I Center a Custom Auto Sized Window

So, here's my scenario - in our app, the content of the window can very likely change, so what I've done is added the following to the pages being opened:

function pageLoad() { fixWindow(); }

function fixWindow() {

// Fix the height to show the buttons in the right place.

var oWnd = GetRadWindow();

var contentHeight = $('#mainContent').height();

var newHeight = contentHeight + 10;

var windowWidth = oWnd.get_width();

$('#popupWrapper').height(newHeight);

$('#popupWrapper').width(windowWidth - 75);

var windowHeight = newHeight + 105;

oWnd.set_height(windowHeight + "px");

// if (oWnd != null) {

// oWnd.center();

// }

}

This works great, except that if I then try to center the window every time, the window will remain open after a postback. How can I correct this so that the window gets centred and works normally?

(Side note: We tried using the auto-size, but it never did a great job of keeping the window sized properly).

Thanks,
Kori

Is there a way to group by category/type in RadListView

I have list of products displayed in a RadListView. I would like to group those products by Category (where Category is a property of the Product class)
Is that even possible using RadListView?

In your samples, you only have basic grouping using a predefined number of items per group.
Thanks,
Gary

Here is the code I'm using:

<telerik:RadListView ID="listViewProducts" runat="server"

onneeddatasource="listViewProducts_NeedDataSource" ItemPlaceholderID="ProductsHolder"

DataKeyNames="ProductCatalogID" >

<AlternatingItemTemplate>

<div class="rlvA" style="height: 160px; width: 200px; margin-top: 5px;

margin-right: 5px; margin-bottom: 5px; padding-left: 5px;">

<table cellpadding="1" cellspacing="1" border="0" width="200">

<tr style="height:60px;">

<td class="header4" ><%#Eval("Products")%></td>

</tr>

<tr>

<td align="center"><%--<asp:ImageButton ID="ImageButton2" ImageUrl="~/Images/Product.jpg" PostBackUrl='<%# Eval("Link")%>' runat="server" target="_blank" />--%>

<asp:ImageButton ID="ImageButton1" ImageUrl="~/Images/Product.jpg" runat="server" OnClientClick=<%# "window.open('" + Eval("Link") + "','',''); return false;" %> /></td>

</tr>

</table>

</div>

</AlternatingItemTemplate>

<ItemTemplate>

<div class="rlvI" style="height: 160px; width: 200px; margin-top: 5px;

margin-right: 5px; margin-bottom: 5px; padding-left: 5px;">

<table cellpadding="1" cellspacing="1" border="0" width="200">

<tr style="height:60px;">

<td class="header4"><%#Eval("Products")%></td>

</tr>

<tr>

<td align="center"><asp:ImageButton ID="ImageButton3" ImageUrl="~/Images/Product.jpg" runat="server" OnClientClick=<%# "window.open('" + Eval("Link") + "','',''); return false;" %> /></td>

</tr>

</table>

</div>

</ItemTemplate>

<EmptyDataTemplate>

<div class="RadListView RadListView_Windows7">

<div class="rlvEmpty">

There are no items to be displayed.</div>

</div>

</EmptyDataTemplate>

<LayoutTemplate>

<div style="width:1150px;" class="RadListView RadListViewFloated RadListView_Windows7">

<div class="rlvFloated rlvAutoScroll">

<div id="Div1" runat="server">

<div id="ProductsHolder" runat="server">

</LayoutTemplate>

Broken image in Image Editor

Hi,

I've just upgraded to the latest and greatest ASP.Net AJAX controls and everything works fine apart from the image that is displayed in the image editor. When I click an image in the image manager the image is displayed fine but when I click the image editor button the image briefly appears but then is replaced by a broken image symbol. If I save the broken image, it then displays fine as a new image within the image manager. I am not using a custom content provider.

Attached is a screen shot showing the image editor.

Any ideas?

Thanks
